Amazing stereo sound effects

This is a demonstration of the
stereo effect. Listening to it, you
feel as though you are in a barber’s
chair, with the barber moving
around you, clipping away at your
hair. As the barber “moves” to your
right, the volume increases slightly
in the right channel and decreases
in the left. Similarly, increases in
the volume of sound from the
clippers give the impression that he
is bringing them closer and closer to
each ear. The illusion demonstrates
our ability to locate sounds in
space; by comparing the inputs to
the two ears, we can work out
where a sound is coming from.
NOTE: Listen through stereo
headphones.
